Electrolysed Water: A natural alternative for removing chemical residue on food.

Following the landmark trial against Monsanto’s weed killer Roundup, questions around the dangers of agricultural chemicals have been reported across the world.

While the replacement of agricultural chemicals with scalable toxic free alternatives is the ultimate goal, residue treatment within the food supply chain offers a more immediate opportunity. Recent studies have found that Electrolysed Water offers a highly effective natural solution to this problem.

ABC News recently reported that Australia’s peak cancer body, Cancer Council Australia, has called for an independent review into the world’s most popular weed killer after it was linked to non-Hodgkin lymphoma. The call for the review comes in the wake of a landmark case in the US that awarded $410m to Californian man Dewayne Lee Johnson, who claimed Monsanto’s weed killer Roundup was a substantial factor in causing his terminal cancer, and that the company failed to warn of the potential risk.

 By now, many consumers have heard of glyphosate, the active ingredient in the herbicide known as Roundup, and warnings about its presence in many of their favorite foods. From oatmeal to granola bars, ice cream to even orange juice, trace amounts of the chemical can be found throughout your local supermarket.

The most widely used herbicide in the world

The Cancer Council Australia is concerned there has not been an independent or formal review of the chemical glyphosate — the active ingredient in Roundup — in more than two decades. Roundup in particular is the most widely used herbicide on the planet and is popular with home gardeners and farmers in Australia alike. Industry wide in Australia there are more than 500 glyphosate-based herbicide products on the market.

Balancing safe and healthy with yield and competitiveness

The optimal use of agricultural chemicals to control pests and disease is a challenging resource management problem, involving informed risk evaluation and management. With primary producers striving to remain internationally competitive and maximize their yield, chemical input costs are on the rise according to recent studies. 

Despite the benefits widely recognized by international agencies arising from the use of agricultural chemicals, there has been increasing public concern worldwide about possible impacts on human health resulting from the application of chemicals and the presence of these entering the food chain once they have been applied.

Electrolysed water as a potential treatment solution

While the replacement of agricultural chemicals with scalable toxic free alternatives is the ultimate goal, residue treatment within the food supply chain offers a more immediate opportunity. A study in the United States recently evaluated the effects of using electrolysed oxidizing (EO) water treatment on the removal of pesticide residues (diazinon, cyprodinil and Phosmet) from spinach, snap beans and grapes, and the effect on produce quality.

The results found that EO water treatment to be more effective than bleach, VegWash and DI water in pesticide removal. In addition, no significant colour or texture deterioration were found on produce samples treated with EO water. It was concluded, EO water can be very effective in in pesticide residue removal.
